First check the correct formula --
Now convert grams to moles using molar mass.
1 moles of a compound  mass equal to its molar mass.
Like H2O molecule
1 mole of H2O = 18.00 g

moles = mass / molar mass

moles = 326.19 / 295.56

moles = 1.10363378..

This is the calculation for FeBr3. It still remains to determine the number of significant figures.
